At 16.00 hours on 27 July 1944, the Stars and Stripes were raised over the central Pacific island of Guam. The symbolism of this moment was not lost on the officers and men who saluted the raising of Old Glory. This was because the first American flag to be pulled down by the Japanese in the Second World War was in Guam, on 10 December 1941, just three days after the attack on Pearl Harbor.

Before the war three of the four main Mariana Islands – Saipan, Tinian and Rota – had substantial Japanese populations and were considered part of the Japanese empire. On the other hand, the largest island of the group, Guam, had been under American administration since the end of the nineteenth century, and its inhabitants saw themselves as Americans. Their liberation would be a ‘psychological high point’ in the long war against Imperial Japan for the people of the United States.

The re-capture of Guam was more than just the recovery of lost territory. It was an essential element of Operation Forager, the US offensive to take the Mariana and Palau islands with the aim of neutralizing Japanese bases in the central Pacific and supporting the Allied drive to retake the Philippines. There was another factor which possibly was of even more significance. Prototypes of the new Boeing B-29 Superfortress were already being flown. The B-29 had an operational range of 3,500 miles, putting the Japanese Home Islands, and even Tokyo itself, well within striking distance of the Marianas. It would be from the Marianas that the strategic bombing campaign which helped bring Japan to its knees in 1945 would be carried out.

The US assault upon the Marianas began with the attacks upon Saipan and Tinian. Then, on 21 July 1944, men of the III Marine Amphibious Corps landed on Guam after the longest preparatory bombardment of the war in the Pacific. For the next twenty days the Marines and the US Army’s 77th Division struggled through dense undergrowth and jungle and over rugged, wooded mountains to eliminate an enemy determined to fight to the death – and die they did. Roasted alive by flamethrowers in dugouts and caves, blasted out of ill-prepared pillboxes by artillery and mowed down by the score in senseless, tactically naïve headlong charges, almost the entire 20,000 strong Japanese garrison was killed.

In the savage struggle throughout the island, American casualties were in excess of 6,000 and many hundreds of civilians were also killed in the fighting. But, after more than two-and-a-half years of Japanese occupation, honor was finally restored in the Central Pacific.
